How do I change a lead time frame?

There are two ways to change a lead time frame; from the lead page or the lead list.

From the lead page, click on the time frame section where you will see a drop-down menu, and you can select one of the time frames available; from Now until 12 months ahead.

Or, from the leads' list, select the lead(s) for which you want to change the time frame and pick the option from the bulk action button.
